Privacy PolicyHigh-Quality and Flight-Critical Transient Voltage Suppressors
Designed to protect sensitive components from electrical overstress due to events like lightning strikes, inductive load switching and electrostatic discharge, a Transient Voltage Suppressor (TVS) limits a voltage spike to a safe level. A TVS diode provides this critical protection by going into avalanche breakdown within no more than a few nanoseconds after a strike, clamping the transient voltage and routing its current to the ground. This solution can significantly improve equipment reliability and reduce losses due to transient voltage-related failures.
These devices can be used in a wide array of applications including military and medical equipment, telecommunications systems, computers and their peripherals. In the sophisticated avionics and aerospace industries, they can also be used to protect the electronics used in engine control systems and in various flight-critical applications including flight control systems, multiple engine control units, actuator controls and a variety of power distribution, environmental control and communications and instrumentation systems.
Our broad portfolio includes both unidirectional and bidirectional discreet plastic TVS devices with power levels ranging from 600W to 130 kW. These solutions are supported by qualification test plans and reliability monitoring that are in line with the best industry-standard practices.

Transient Voltage Protection for Avionics and in Robust Environments
There is an increasing need to provide multi-stroke and multi-burst lightening protection in a variety of applications, especially in new aircraft that are being built with mostly composite bodies. The RTCA DO-160 standard defines the test standards for these hazards in aeronautic products. Learn how our high-reliability plastic TVS devices are uniquely suited to address these requirements.
